On 2/18/2019 took the F-150 to Mathews Ford Marion Ohio service to address several issues. First, the tailgate had unexpectedly opened striking a trailer jack and damaging the tailgate. Tailgate opening while driving with cargo could result in cargo falling onto roadway. Damaged tailgate remains on the truck and is available for further inspection. Second, the owner heard rubbing/grinding noises when switching in and out of 4 wheel drive. The service technician could not replicate either issue. On 11/29/2023 took the F-150 to Leroy's Service Center in Delaware Ohio as the dashboard indicated several messages including required oil change (although odometer showed an oil change was not needed for another 3,000 miles compared to oil change sticker on windshield), a large yellow wrench adjacent to required oil change message, a small yellow wrench below required oil change message, and a yellow check engine light. Twice there was sensation of slipping (applying gas but no movement). Once parked in Leroy's lot the truck could not be started. Service technicians suspected LEAD frame failure. Service technician replaced the original LEAD frame with Ford Part numbers 2592734 and aL3z-7g276-d 1x (off replacement part box). I retained malfunctioning part for inspection if desired. Numbers off the malfunctioning part include aL3p-7g276-ak a9-21416-0998 c108p; Ford b556d; 3264 487 321 09 330743; Continental 3a8214160008 a2c53308751. Malfunctioning transmission while driving could cause unexpected vehicle slowing or stoppage. In summary, experienced unexpected tailgate opening, History of transmission issues (unexpected sounds when switching into or out of 4 wheel drive), and failure of the LEAD frame with slipping and inability to start vehicle after it was parked.

The transmission Lead Frame has failed. This is the same problem we had with our 2013 F150 under campaign number 19N01. This is a common problem with the ford transmission that continues to occur. Ford should be made to support this issue since it can lead to severe accidents if the transmission was to lock up or shift to a lower gear abruptly while in motion.

2016 FORD F150 WITH 55,000 MILES.STARTED DRIVING VEHICLE, ENGINE RPM DROPPED, ENGINE MISSING AND SHAKING. NO THROTTLE RESPONSE. VEHICLE JUST IDLED HORRIBLY. DASH HAD LARGE WRENCH SYMBOL AND AN "ACCUTRAC SERVICE NEEDED" WARNING. i TURNED OFF IGNITION, RESTARTED VEHICLE. SAME RESULTS. I DID THIS 4-5 MORE TIMES. LAST TIME VEHICLE IDLED OKAY AND ACCELERATED. DROVE THE VEHICLE 60 MILES HOME WITH NO THER ISSUES. CHECKED WITH AN OBD-II DIAGNOSTICS AND GAVE 2 CODES: P2111 THROTTLE CONTROL SYSTEM-STUCK OPEN AND P2112 THROTTLE ACTUATOR CONTROL SYSTEM-STUCK CLOSED. NOW, NOW WARNING LIGHT OR ANY INDICATION OF PROBLEM ON DASH. NO WARNING LAMPS PRIOR TO PROBLEM. SAFETY WAS AT RISK BECAUSE WITHOUT WARNING, PULLING OUT INTO HEAVY TRAFFIC AND LOSING THE ABILITY TO ACCELERATE WITH TRAFFIC COULD CAUSE A SERIOUS ACCIDENT. LOOKING THIS PROBLEM UP IN AN ONLINE FORD F150 FORUM INDICATES THIS IS A FAIRLY COMMON PROBLEM. WHY HAS THERE BEEN NO RECALL FOR THIS POTENTIALLY DEADLY ENGINE FAILURE CIRCUMSTANCE?

Extreme corrosion to the transfer case casting around all of the fasteners. The corrosion is so bad that the case is starting to separate and leak fluid. There is a severe vibration in the drive train and it is believed to be the cause.

On three occasions my vehicle went into a -??FAIL-SAFE MODE-??. The first occurrence happened while I-??m driving on dry pavement at approx 45mph. Unexpectedly the engine shakes and slowed the vehicle to 5mph while I-??m in medium to heavy traffic. I was on a two lane road and had to quickly pull off to the shoulder. The second occurrence was while I was merging in heavy traffic and accelerating into the flow of that traffic. As the FAIL-SAFE MODE made my vehicle rapidly slow the cars behind me had to swerve and make fast lane changes. I engaged my emergency flashers to caution other drivers until I could escape the roadway on to a private driveway. The third occasion was similar to the first. Each time the FAIL-SAFE MODE happened a warning message appeared on my dash with a description of the problem and a large wrench appeared. Two different messages appeared. Twice the message was regarding a failure in the TRACTION. CONTROL. Once the message was about a problem with the HILL DESCENT CONTROL. After each event I turned off the engine, waited a few minutes, restarted the engine and was able to drive away like nothing happened. The owners manual instructed me to stop driving and have the vehicle towed to the dealer. The dealer has now had my vehicle for a month. They computer on this vehicle erases the code when the engine is restarted. So they cannot fix this problem. I asked the service manager at the dealership to reach out to the manufacturer which he did. The manufacture-??s response was -??without a code we can-??t diagnose the problem, give the vehicle back to the guest-??. This is a serious safety issue, a vehicle that would come to a crawl while in traffic. This would put myself and other drivers at risk. The dealer wants me to drive the vehicle to have the issue duplicate itself and then what?

I have replaced four turbos directly from board on the driver side only and now my transmission decided to lock up on me on the freeway at 75 mph and they're saying that it was a lead frame problem which Ford doesn't have any they're on backorder for months

The vehicle experienced intermittent starting issues for a few days, then left my son stranded in the middle of an intersection after it would not crank. Was able to finally get it started and get it home, but had to get it towed to the dealership the next day. I was able to get a code with a scanner that pointed to a fault in the transmission range sensor circuit. I did some research and discovered the problem was likely a defective molded lead frame inside the transmission. There have been many instances when this part has failed and there was a known problem with earlier model year vehicles that had an extension of the factory warranty. I paid to have the repair completed at a cost of $1430.31 but I believe this should have been a service bulletin item or a recall because of previously reported problems. I was without this vehicle for over 2 weeks.

My 2016 Ford F-150 supercab is leaking transmission fluid. Noticed the gasket is leaking from the transfer case. Took it to the dealership and they said that it can not be repaired and needs to be replaced because it is coroded and it will take a couple of months to get the parts because the special bolts are on back order. The replacement will cost me $3900 and they said i should not be driving it. I can go without a vehicle for 2 months while waiting for parts. Meantime I have to drive it while it's leaking. Have no choice can't afford to rent a car I have heard this happening to others having the same problem where the bolts are coroded and leaking with the same Borg Warner transfer case that was put on by Ford factory

The ford 2.7 liter eco boost engine has a design flaw that leads to the engine oil pan to leak around the seal which creates an environmental concern for leaking oil on the ground and also poses a fire risk as the oil could potentially contact something hot and could flame up. This is a known issue that many 2.7 liter eco boost engine owners have had to deal with and some of them have had to make the costly repair more than once. Ford only has issued a TSB 23-2083 for this issue and will not do a recall unless the NTSB says per their customer service at Ford corporate who handled my case that I had opened up.

My vehicle check engine light and wrench light came on suddenly. My transmission got stuck in 5th gear. Upon arriving to the stop light the transmission wouldn-??t downshift leading me to start off very slow. The car behind me almost rear ended me. Once I was up to about 50 mph, the transmission downshifted to 2nd gear obviously at high rpm-??s and it felt like someone rear ended me. I see this was an issue that had a recall issued on 2011-2013 F150-??s. I believe there is another issue or one that wasn-??t resolved. There are several complaints online about the part being on backorder for months, which was also confirmed by my dealership once the diagnostic was completed. My vehicle is a 2016 with only 59k miles on it. This $1100 repair should be covered by Ford Motor Company.
